Reflected XSS in Ultimate WooCommerce Auction Pro 2.4.5 and earlier allows remote attackers to execute script in an administrator session. The uwa_auctions_bids_list page outputs an attacker-controlled parameter without sanitization or escaping. Exploitation requires a high-privilege user to open a crafted request, after which the script runs with that user's browser privileges.
